position. Warning light should come on and stay on.
2) When ignition switch is turned from START to ON position,
warning light should come on for one second, and then go out. If
warning light functions as specified, go to step 3). If warning light
does not function as specified, see appropriate trouble shooting test:
* IGNITION SWITCH IN ON POSITION (ENGINE NOT RUNNING),
ANTI-LOCK WARNING LIGHT INOPERATIVE
* AFTER ENGINE STARTS, ANTI-LOCK WARNING LIGHT REMAINS ON
* IGNITION SWITCH IN START POSITION, ANTI-LOCK WARNING LIGHT
INOPERATIVE
* IGNITION SWITCH IN ON POSITION, ANTI-LOCK WARNING LIGHT
BLINKS TWICE. IN START POSITION, LIGHT STAYS ON. WHEN
IGNITION SWITCH IS CYCLED FROM START TO ON POSITION, LIGHT
BLINKS ONCE, THEN TURNS OFF
3) Test drive vehicle. If ANTI-LOCK warning light does not
come on at low speed, go to next step. If light comes on at low speed,
motor relay, solenoid valve or Wheel Speed Sensor (WSS) malfunction is\
indicated. Go to step 6). If insufficient braking force or ABS
malfunction exists, go to next step. If none of listed symptoms exist,
go to step 6).
4) Check conventional brake system components for proper
operation. Check for mechanical lock of hydraulic unit solenoid valve.
Check for plugged hydraulic line in hydraulic unit. Repair or replace
as necessary. If hydraulic unit is okay, go to next step.
5) Ensure WSS rotor gap is correct. See WHEEL SPEED SENSOR

Using ANTI-LOCK Warning Light
1) To retrieve stored DTCs, locate Data Link Connector (DLC)\
under left side of dash. Turn ignition off. Ground DLC terminal No. 1.
See Fig. 8 .
2) If DTCs are stored in ECU memory, ANTI-LOCK light will
begin to flash intermittently. Long flashes represent first digit of
DTC; short flashes represent second digit. For example, 4 long flashes
and 3 short flashes indicate DTC 43. If 2 or more DTCs are stored,
lowest number will be displayed first. DTC 51 will always be displayed
if valve relay is removed.
3) After recording DTC(s), see DTC DEFINITION table and
perform appropriate DTC test(s) under DIAGNOSTIC TESTS. If no DTCs are
stored, ANTI-LOCK warning light will flash constantly.

Retrieving Codes Using Oil Temperature Warning Light
1) Using jumper wire, ground DLC terminal No. 1. See Fig. 6.
Note number of flashes from oil temperature warning light on
instrument panel. See Fig. 7. If normal system operation exists, oil
temperature warning light will blink 2 times per second. See Fig. 8.
2) If system is operating correctly and no DTC exists, turn
ignition off and remove jumper wire. If DTC exists, oil temperature
warning light will flash once every 2 seconds. The number of flashes
will equal first digit of DTC. After a pause of 2 seconds, second
digit will be displayed. Oil temperature warning light will flash once
every half second for second digit. See Fig. 8.
3) If more than one DTC exists, next DTC will be displayed
after pause of 3 seconds. Smallest DTC number will be first. DTCs will
be repeated.
4) Once DTC is obtained, determine probable cause and
symptom. See DIAGNOSTIC TROUBLE CODE IDENTIFICATION table. To trouble
shoot DTC, see DIAGNOSTIC TESTS. Turn ignition off and remove jumper
wire.
NOTE: Once repairs have been performed, DTCs must be cleared from
TCM memory. See CLEARING DIAGNOSTIC TROUBLE CODES (DTC).

2) Use scan tool for system input check according to
operating instructions provided with scan tool. Connect leads of
analog voltmeter between cruise control terminal and ground terminal
of data link connector. See Fig. 35.
3) Turn ignition on. To display results of input check, move
cruise control SET switch to ON position. Then turn MAIN switch to ON
position. Within one second, activate RESUME switch. Codes will
display if circuit tested is okay. See Fig. 3.
